Deciding whether to sell Sintana Energy (SEI) shares depends entirely on an individual investor's risk tolerance, portfolio strategy, and timeline regarding speculative resource equities. Investors comfortable with high volatility who wish to maintain exposure to major upcoming offshore drilling catalysts in Namibia and South America often choose to hold, whereas risk-averse investors concerned with pre-revenue dilution, capital-raising needs, or fluctuating micro-cap market conditions may consider trimming or liquidating positions.
